Getting #550 5.7.1 Recipient rejected (R1) when sending from new Exchange 2007 server
Posted on 2010-11-26
I have just installed a new server MS SBS 2008 and have set up Exchange 2007. I am able to receive all emails but when I try to send Im getting rejected:
#550 5.7.1 Recipient rejected (R1) ##
That is how emails bounced back from any server that I send. I did have a SBS 2003 with exchange at the same location so Im sure it is not a Reverse DNS issue. I did check for blacklists but that is not the case here either. I wonder if there is something on the configuration of the server itself that could be causing this.
Here is the detail email that I get:
Delivery has failed to these recipients or distribution lists:

The only thing that I see strange is that is using the .local server to go out, maybe I need to change it to go out with .com but I dont know how to do that.
Anyone has any ideas?
